References
1849
• September 14, 1849
– Born in Ryazan, Russia
– Father was a town Priest
1860
• Began school at age 11
– Because of a childhood accident
Pavlov was forced to begin school
late.
– He attended church school and
seminary school.
1860 Continued
– His accident and related time in the
care of doctors may have sparked
his interest in medicine.
– He read Charles Darwin’s The Origin
of the Species and decided that he
was more interested in science than
seminary.
1870
• Left seminary to study science at
the University of St. Petersburg
until graduation in 1875.
1870 Continued
– His scientific study in physiology led
him to the discovery and study of
conditioned response.
1875
• Began graduate work at the
Military Medical academy.
PERSONAL LIFE
1881
• Married pedagogical student,
Sara, who was devoted to his
comfort and his work. Pavlov
attributed his work to her.
1881 Continued
– Had he not married his wife, he
might not have continued his
research without her support.
Contributions to Science
1883
• Received doctorate. Finished
dynamic nerves of the heart.
1890
• Professor of Physiology at the
University of St. Petersburg
Institute of Experimental Medicine.
– Being employed by this research
institute allowed Pavlov access to
funds and the time to complete his
research.
1897
• Published Lectures on the function
of the principle digestive glands.
1903
• Published Conditioned Reflexes
– Studying digestive physiology led Pavlov
down and “accidental” path which allowed
him to contribute to the study of
psychology.
– He studied digestion in dogs and linked
salivation to the nervous system.
– He discovered that without salivation,
digestion did not take place.
1903 Continued
– His digestive experiments led him to
the study of conditioned reflexes.
He rang a bell, fed the dogs, rang a
bell, fed the dogs and so on.
– Then he rang the bell and watched
as salivation would occur.
– This provided the impact of
conditioned reflexes.
1903 Continued
• An illustration of how conditioned
reflexes works:
1903 Continued
– Pavlov also studied repression of
this impact in that he would ring the
bell and give no food and eventually
the dogs considered the bell a wrong
stimulus and the response was
repressed.
Taking Over where Pavlov
Left off
• Pavlov’s work inspired the work of
John Watson and he applied it to
the Behaviorist Theory in 1913. In
this way, Pavlov’s work was
continually studied and added to.
1904
• Received Nobel Prize for
physiological and medical
research, The Centrifugal Nerves
of the Heart.
– Pavlov was the first Russian and
physiologist to receive the Nobel
Peace Prize.
1924
• Resigned from St. Petersburg
Institute of Experimental Medicine
1935
• His youngest son died.
– The death of his son probably played
a role in his own death a year later,
but that is not a known fact.
1935 Continued
• The government built a laboratory
for his work on conditioned
reflexes.
1935 Continued
– The laboratory built for him validated
his efforts and encouraged further
study.
Pavlov’s Work Continues
• Further study continues today on
Pavlov’s Theory of Conditioned
Reflexes.
– This would be his greatest contribution to
human learning.
– His techniques have been modified and
are used today to treat humans in antiphobia therapy.
– Patients are taught to relax and then use
the relaxation technique while being
exposed to the phobia.
– Commercials can be attributed in part to
Pavlov, at least how they are to function
can be. We see the messages, associate
them with the product, then think we need
the product.
1936
• February 27 – Ivan Pavlov died of
liver cancer in Leningrad at the
age of 87.
• Pavlov proclaimed himself to be a
physiologist, not a psychologist.
